Question

If five times the measure of an angle is decreased by 30, the result is the same as when two times the measure of the angle is increased by 18. What is the measure of the angel

Answer 1

16

Explanation:

Let "a" represent the measure of the angle. Then ...

5a -30 = 2a +18

3a = 48 . . . . . . . add 30-2a

a = 16 . . . . . . . . . divide by 3

An angel is beyond measure, but this angle has measure 16.
